MAT.

Specification of Letters Patent.

Patented Aug. 4, 190s.

Application mea May 22, 190s. serial No. 318,202.

To all whom it may concern:

Y Be it known that I, THOMAS C. MOPHER- soN, a citizen of the UnitedStates, residing at Beaver Falls, in the county of Beaver and State ofPennsylvania, have invented a new and useful Mat, of which the followingis a specification.

This invention relates more particularly to metallic mats, and is in thenatureof an improvement on the mat disclosed in application, Serial No.303,507, filed Feb. 21, 1906. The principal object in the present caseis to provide novel reinforcing devices that will secure rigidity in themat, and prevent its becoming misshapen, said devices being so formedthat they may be readily placed in position, will accommodate themselvesto in-y accuracies due to the formation of the mat strips, and willproduce a more ornamental effect.

In the accompanying drawings z-Figure 1 is a plan view o a portion of amat, showing the improved reinforcements forming 4a part of the same.Fig. 2 is a detail horizontal sectional view therethrough. Fig. 3 is alan view of a slightly different form of mat avinthe reinforcementstherein.

imilar reference numerals designate corresponding parts vin all thefigures of the drawings.

In the embodiment Villustrated in the first two figures, the mat iscomposed of sections 4, each section comprising a tortuously formedsectional strip, the said sectional strip being bent into oppositely disosed open loops 5, forming longitudinal side web elements 6 and crosswebs. The closed ends of the loo s 5 of one section enter the open ends,

of the oops of the adjacent section. Pivot .rods 7 connect the adjacentsections, said againstthe adjacent longitudinal Web elements 6 of themat section. The end webs in like manner abut against the end Webs ofthe evices consist` loops in which they are placed. One ofthe pivot rods7 passes through the outer ends of said portions 10. The doubled end 11of the through the doubled end, as shown so that the cross web of thereinforcement is located between the pivot rod and the cross web of theloop in which said reinforcement is located.

The same reinforcements are shown in a slightly different form of mat inFig. 3. In this structure the oppositely disposed loops 5a of the matsections 4a are formed from a continuous strip instead of a sectionalstrip, and the free ends 'of the end loops are separated by coiledsprings otherwise the structure is substantially the same.

There are several distinct advantages for the peculiarly shapedreinforcing devices. In the first place, they can be much more quicklyplaced in position than the devices shown in the application to whichreference has been made. In forming the loops 5 and 5a' of the matsections, the dies in time become worn, and consequently the width ofthe doubled ends will vary. With the plain U-shaped devices, such as areshown in the From the foregoing, it is thought that the construction,operation, and many advantages of the herein described invention, willbe apparent to those skilled in the art, Without further description,and it will be understood that various changes in the size, shape,proportion, and minor details of construction, may be resorted towithout departing from the spirit or sacrificing any of the advantagesof the invention.

I-Iaving thus fully described my invention, What I- claim as new, anddesire to secure by Letters Patent, is

1. In a mat, a plurality of sections comprising reversely disposedloops, certain of the doubled ends of the loops of one section beinglocated in the open ends of the adjacent section, pivots passing throughsaid doubled ends and being spaced from the doubled portions thereof,and reinforcements located inthe end loops of each section and havingside portions located against the sides of the same, said reinforcementshaving doubled portions engaged with the pivots and disposed in spacedrelation to the sides of the section loops, in which they are locatedbeing furthermore located in the spaces between the pivots and thedoubled ends of the section loops,

2. A mat comprising a plurality of sections, each section consisting ofa strip formed into oppositely disposed loops having open and closedends, reinforcing loops located in the terminal loops of each sectionand having open ends, the open ends of the section loops in which theyare located being furthermore provided with closed ends of less widththan the closed ends of the section loops in which they' are locatedand. abutted against said closed ends while spaced from the sides ofsaid section loops, the closed ends of the loops of one section enteringthe open ends of the loops of the adjacent sections, the closed ends ofthe terminal loops in like inanner entering the open ends of thereinforcing loops of the adjacent sections, and pivots passing throughsaid ends and constituting connections between the various sections.

In testimony, that I claim the foregoing as my own, I have heretoailixed my signature in the presence of two witnesses.
